Hi there and welcome
you mean the password ***** unlock the screen on the iPad correct?
Please let me know
You will have to reset the iPad, there is no other way to remove this.
To do the reset
Connect the iPad to the computer and open itunes
Hold the power and home button down until you see
"iTunes has detected an iPad in recovery mode..."
Click Restore iPAd, let this complete and it should now work
Let me know the results please
Its the process to rest the device and remove the lock.
What issue did you encounter when doing my instructions ?
